TeYT27e kitea whānuitia ana i roto i ngā keri kōhatu karāhe me te māpere nā te mea he pumau te ara keri. Mā te tika o te tūnga ka māmā ake te wehewehe i ngā poraka i runga i ngā rārangi kōhatu tūturu, ka whakaitihia te para i te wā e tangohia ana.

 

Ahakoa te hanga pereti mō ngā kaupapa whare, ngā kōhatu nunui rānei mō te whakapaipai whenua, ko te YT27keri tokae whakarite ana i te kounga teitei o te tango me te putanga pumau — he mea nui mō ngā kaiwhakarato kohatu o ēnei rā.

 

Ehara i te mea he āhuatanga hangarau noa iho tēnei arotahi tonu ki te tika; he urupare tika ki ngā pēhanga e piki haere ana e pā ana ki te umanga keri kohatu. I te piki haere tonu o te hiahia o te ao mō ngā whare kounga teitei me ngā kohatu whakapaipai, kei te pēhia ngā kaiwhakahaere i waenga i te hiahia mō te hua teitei ake me te hiahia kia whakamahia ngā tikanga pumau ake, whai hua ake. Ka aro atu te YT27 ki tēnei wero tuturu, ka huri i te taahiraa tuatahi nui o te tango mai i tētahi toi rerekē ki tētahi pūtaiao whakahaeretia. Ko tōna hanganga pou pakari me te pūnaha whakamātao matatau ka ārai kaha i ngā wiri me te hikoi-moka e pāngia ana e ngā keri tuku iho. Ko te hua o tēnei he poka poka tika tonu, i ngā wā katoa.

 

He nui ngā painga o tēnei pūmautanga tuatahi. Ina tika te whakarite o ngā kōhao keri, ka whai ngā kani waea taimana, ngā poro rānei i te ara e hiahiatia ana, me te kore e peka ke. Mā tēnei ka taea e ngā rangatira o te rua keri te whakamahi i ngā rārangi pakaru me te kiko o te kōhatu, ka "wetewete" i te papa kōhatu, kaua e pakaru noa. Ko te pānga tonu he whakaiti nui i te kōhatu pakaru me te kore e taea te whakamahi. Mō tētahi rua kōhatu karāhe noa, ka taea e tēnei te whakaputa i te hua o te 15% neke atu rānei mai i te rahinga papa kōhatu kotahi, ka huri i ngā mea i mua he para hei rauemi utu nui, ka taea te hoko. Ehara i te mea ka whakanui ake i te hua engari ka roa ake te roa o te mahi o tētahi papa kōhatu, he painga rautaki nui.

 

I tua atu i te hua, ko teYT27 wiri toka waewae hauHe mea hanga kia manawanui i roto i ngā taiao tino uaua. Kua arotauhia tōna pūnaha hiko mō te keri iti-RPM, te keri taipana teitei, e tuku ana i te mahi pumau me te kore e hiahiatia he taumahatanga ki ngā wāhanga. Ko te tikanga he iti ake te wā whakatā mō te tiaki me te iti ake o ngā utu whakahaere i te roanga o te roanga o te mīhini. Ka whakaitihia e te kāpata ngāwari, ergonomic te ngenge o te kaiwhakahaere, e whakarite ana ka taea te pupuri i te mahi keri teitei puta noa i te huringa katoa. Hei tāpiri, ko te pakaru ma ma i tutukihia mā te keri tika ka tino whakaitihia te tukatuka tuarua e hiahiatia ana mō ngā poraka i te wheketere. Ka puta mai ngā poraka mai i te rua keri me ngā taha tapawhā me te iti ake o ngā pakaru moroiti, ka tere ake te huringa o ngā kani me ngā mīhini whakakanapa i raro iho.

 

I roto i tētahi ahumahi e whakairohia ana ngā taha mai i ngā mirimita o te kōhatu, kua noho te YT27 hei taputapu tino nui. He nekehanga mārama tēnei mai i te tango kaha ki te whakaora atamai, e āhei ai ngā kaiwhakarato ki te whakatutuki pono i ngā whakaritenga tika o ngā kaupapa hanga me te hoahoa nui. Mā te whakanui ake i ngā mea e tangohia ana mai i te whenua me te whakaiti i ngā mea e toe ana, kāore te YT27 e keri noa i ngā kōhao - engari ka wetekina te uara, ka whakatakoto i tētahi paerewa hou mō te whai huatanga me te kawenga i roto i te keri kōhatu hou.
